Gandalf (Pure Maths Student Seminar): A theorem in topology with a view towards quantum entanglement

Presented by Henry Maxfield, Durham

4 December 2014 15:00 in CM107

A central property of quantum mechanical systems is entanglement: knowledge of the parts does not constitute knowledge of the whole. It turns out that in some circumstances, quantifying entanglement is equivalent to a classical problem, of finding minimal surfaces. I'll wave my arms a bit to motivate where this comes from, and then do some proper maths to prove a theorem in algebraic topology, which tells us which topological class of minimal surfaces to consider in the problem.
